Chongqing Taonan straight seam welded pipe is good equipment. Stable gas pipelines. National standard steel pipe standards. Introduction The strong oxide film on the surface of thick-walled steel pipes makes stainless steel have excellent corrosion resistance in all water quality, including soft water. Corrosion resistance, and also has good erosion resistance. The strength of spiral welded pipes is generally higher than that of straight seam welded pipes. Welded pipes with larger diameters can be used with narrower blanks, and welded pipes with different diameters can also be used with blanks of the same width. Q345B straight seam welded pipe, but compared with straight seam pipe of the same length, the weld length is increased by 30——, and the speed is good. Therefore, most of the relatively welded pipes use straight seam welding, and large-diameter welded pipes mostly use spiral welding. Advantages of spiral seam steel pipe specifications Spiral pipe and its standard classification: Q345B straight seam welded pipe for conveying fluid under pressure (SY-8 is mainly used to transport petroleum. Beijing-Shanghai high-speed railway and the existing Beijing-Shanghai railway (formerly Jinpu-Puhan Railway and Shanghai-Nanjing Railway) are two basically parallel railways, a few meters apart. In fact, there is a parallel railway along the Shanghai-Nanjing Line: the Shanghai-Nanjing Intercity Railway is adjacent to the existing Shanghai-Nanjing Railway and basically shares stations, similar to the Beijing-Tianjin Intercity Railway The test has been completed and will be put into use in July this year. In the future, the short-distance passenger dedicated line from Shanghai to Nanjing will use Q345B straight seam welded pipe. The surface Rockwell hardness tester is also suitable for testing the hardness of surface quenched workpieces. The surface Rockwell hardness tester has A variety of scales can be selected. Various surface hardened Hunan straight seam welded pipes with an effective hardening depth exceeding 0.1mm can be tested. Although the accuracy of the surface Rockwell hardness tester is not as high as that of the Vickers hardness tester, it is used as a quality management and qualified inspection method for heat treatment plants. It has been able to meet the requirements. Moreover, it also has the characteristics of simple operation, convenient use, low, fast measurement, and direct reading of hardness values. The surface Rockwell hardness tester can quickly and non-destructively inspect the batch of surface heat-treated Hunan straight seam welded pipes. This is of great significance for Hunan straight seam welded pipe processing and machinery factories. Super-large diameter double-welded straight seam steel pipes in the axial direction Under the effect of pressure, the steel pipe is axially and radially compressed and hooped in tension, and the concrete is compressed in all directions. The steel pipe and the concrete are mixed in such a way that even if the concrete surface is stressed, the steel pipe with super large diameter double welded seam is welded. It will reduce the cross-section of reinforced concrete columns by 60%, which will expand the use of the building. Chongqing Taonan small steel, thin steel plate, steel strip, silicon steel sheet, or thin-walled steel pipe, various cold-rolled, cold-drawn steel As well as high and easily corrosive metal products, they can be stored in warehouses. Affordable prices Despite the steel plant's production limit in the early implementation period is still less than expected, Q345B straight seam steel pipes, but with the increase of supervision and the deepening of production restrictions, the environmental protection limit in the later period It is not necessary to doubt that the production implementation will become more stringent. At present, no matter whether it is steel market inventory or steel plant inventory, Q345B straight seam steel pipes are at a low level. With the deepening of production restriction in the later period, Qingye Nannan has good equipment for straight seam welded pipes, and the subject of supply contraction will still be the most important factor supporting steel prices. Looking at the overall growth rate of domestic real estate and infrastructure investment in October, the daily average output of Q345B straight seam steel and crude steel Momentum drop: It is the steel that puts the metal in a closed cell, and applies pressure at the end to make the metal extrude from the prescribed die hole to have the same shape and size of the finished product. It is mostly used for non-ferrous metal steel. Free consultation The blank used by Weifang welded steel pipe is steel plate or strip steel, which is divided into furnace welded pipe, electric welded (resistance welded) pipe and automatic arc welded pipe due to different welding processes. It is divided into two types: straight seam welded pipe and spiral welded pipe due to different welding forms. .Because of its end shape, it is further divided into round welded pipes and special-shaped (square, flat, etc.) welded pipes. Q345B welded pipes are divided into the following varieties due to their different materials and uses. Q345B welded pipes are partially welded after the extrusion process. This is the result of the stress in the heat-affected zone of the weld during welding. Due to the normalization of a certain width of both sides of the weld of Q345B welded pipe, the hardness of the base material is increased, and the welded pipe is not sufficiently annealed after welding. There tensile residual stress exists, the common result of these factors are generated at the next weld cracking 1MM when compressed, the weld material is often better than the mechanical properties of the substrate, so as not crack the weld. Welded steel pipe, also called welded pipe, is a steel pipe made by welding steel plates or strips after being rolled. The shelf pipe often used in construction is also a kind of welded steel pipe. It is made by using hot-rolled strip steel after being rounded and welded. The good technology of welded steel pipe is simple and efficient. Chongqing Taonan straight seam welded pipe. Good equipment. Stable welded steel pipe. Welded pipe is a steel pipe welded from steel plate or steel strip coil, and its general size is 6 meters. Welded steel pipe has the advantages of simple technology, high efficiency, many varieties and specifications, and low equipment investment, but its comprehensive strength is lower than that of seamless steel pipes. Since the 1930s, with the rapid development of continuous rolling of high-quality strip steel and the improvement of welding inspection technology, the quality of welds has continuously improved, the variety and specifications of welded steel pipes have continued to increase, and seamless steel pipes have continued to develop. Pipelines have been replaced by more and more fields. Welded steel pipe is divided into straight seam welded pipe and spiral welded pipe according to the welding form. According to good classification: process classification-arc welded pipe, resistance welded pipe (high frequency, low frequency) gas welded pipe, furnace welded pipe.

Chongqing Taonan straight seam welded pipe is a good equipment. Stable spiral welded pipe: It is to roll a low-carbon carbon structural steel or low-alloy structural steel steel strip into a tube blank at a predetermined spiral angle (called forming angle), and then weld the tube To make it, it can be made of a narrow strip steel and a large diameter steel pipe. Spiral welded pipe is mainly used for oil and gas transmission pipelines, and its specifications are expressed by outer diameter * wall thickness. Spiral welded pipe has single-sided welding and double-sided welding. The welded pipe should ensure the hydrostatic test, the tensile strength of the weld and the cold bending performance must meet the requirements. Promise that the demand for trustworthy spiral welded pipes will not collapse in the short term. From the perspective of both the supply and demand of spiral welded pipes, we believe that demand will not collapse in the short term, and that the supply of spiral welded pipes will not increase sharply. Tier turning point-that is, from a unilateral rise to a high level of shocks, the next few months may be a period of strong and weak transition in steel prices. The futures spiral fluctuated and fell below the 4000 mark. Market sentiment appeared. Spiral welded pipes fell sharply in some areas. The trading atmosphere remained weak. Until the futures spiral stabilized, the market turnover was slightly better. Back to the downturn. The integrity management steel pipe can be divided into hot rolled steel pipe and cold rolled steel pipe according to the rolling process; Q345B straight seam steel pipe can be divided into seamless steel pipe and welded steel pipe according to whether there is a seam in the steel pipe. Seam steel pipe can be divided into high frequency welded pipe, straight seam submerged arc welded pipe, spiral submerged arc welded pipe and so on. Straight seam high-frequency resistance welded steel pipe and high-frequency straight seam welded pipe are a kind of good process steel pipe, and high-frequency straight seam welded pipe is an abbreviation. Both of these are ERW steel pipes. "ERW steel pipe" is a high-frequency straight seam resistance welded pipe, English Electric Resistance Welding (abbreviated as ERW, stainless steel welded steel pipe for fluid transport): It is mainly used to transport low-pressure corrosive media.
